After losing 9 chickens in 8 days (yes, days not nights) to a raccoon, the traps are still empty, but I have something better ... It's 16 x 16, kind of small for my remaining 18 chickens, but it's all we could afford with DH out of work. We are planning another as we can do it. It spans both coops so they will still be locked in at night. So far it has a wire roof, but eventually we are thinking a tin roof might be better for protection from the weather. By the time he is finished, it will have a converted wooden ladder for perching, too.
